Two new thermotropic liquid crystalline polymers (TLCPs) were synthesized. One is a dimesogenic TLCP having a flexible hexamethylene spacer in the main chain, the other is a rigid type main chain TLCP having alkoxy side chains on the terephthaloyl group of the polymer. Blends of TLCP with PBT were melt spun at different LCP contents and different draw ratio to produce a monofilament. Maximum enhancement in the ultimate tensile strength was observed for the blends containing 5% LCP at any draw ratio, and decreased with further increase in LCP content. The initial modulus monotonically increased with increasing LCP content. The tensile properties of the rigid type LCP blends were higher than those of the flexible main-chain LCP blends.
